Overview
The DG401DYZ-T is a dual single-pole single-throw (SPST) normally open analog switch manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 5V to 34V for single supply or ±5V to ±17V for dual supply configurations. The device features a maximum on-resistance of 45 ohms with a channel-to-channel matching of 3 ohms. Switching times are specified at a maximum of 150ns for turn-on and 100ns for turn-off. Key electrical characteristics include a charge injection of 60pC, off-state leakage current of 500pA, and a crosstalk specification of -90dB at 1MHz. The component is housed in a 16-SOIC package and supports an operating temperature range from -40°C to +85°C.
Feature Summary
- Dual SPST configuration providing two independent signal paths
- Low on-resistance with tight channel-to-channel matching for precision applications
- Reduced charge injection simplifies sample-and-hold circuit designs
- TTL and CMOS compatible digital inputs for flexible logic interfacing
Applications
- Sample-and-hold circuits requiring low charge injection
- Data acquisition systems utilizing TTL/CMOS logic interfaces
- Signal routing in instrumentation equipment
Procurement Notes
Verify the specific suffix 'T' indicates tape and reel packaging when sourcing. Confirm RoHS compliance status as legacy variants may differ. Ensure the supplier provides valid traceability documentation for this discontinued part number. Cross-reference the manufacturer date code against project lifecycle requirements.
Selection Notes
Select this component when dual isolated analog switching is required with moderate speed and low distortion. Compare on-resistance stability against alternative series if high-voltage signal handling exceeds 34V. Verify that the 16-SOIC footprint aligns with existing PCB layout constraints. Consider thermal dissipation limits if driving loads near the maximum current rating.
Part Context
This device belongs to the DG401 family of monolithic CMOS analog switches. It serves as a drop-in replacement for older discrete switching solutions. The technology utilizes a silicon-gate process to prevent latch-up. It offers improved performance over previous generations regarding switch time and resistance linearity.
Replacement Considerations
Public confirmed substitute part numbers include DG401DYZ. Verify pin compatibility before substitution. Check if the replacement variant maintains the same SOIC-16 package dimensions and electrical specifications.
